I'm still new at this. So far I've just tried to find a good, stiff middle of the road load for this 45-70. This past week I've been working on another load but with IMR4198 (350gr bullet).

I want my son to shoot this thing so I've loaded some light ones. The data given by Hornady for the IMR4198 minimum is 32gr powder. Will I have to stuff some filler in the cartridge for this?

A very little Dacron filler can be used to keep the powder toward the primer. A light tuft, just enough to hold the powder down toward the base. You do not have to fill the entire space.

45-70 Gov't light loads.

144 grain collar button or 146 grain round ball
8 grains Unique 1135 fps
15 grains 2400 1300 fps
18 grains 4227 1390 fps
20 grains 4198 1350 fps

193 grain 455 Webley revolver bullet sized .457" (mold is rare)
10 grains Unique 1350 fps
16 grains 2400 1260 fps
18 grains 2400 1365 fps
18 grains 4227 1320 fps
19 grains N-200 1330 fps
21 grains 4198 1350 fps

210 grain bullet (mold and manufacturer unknown)
10 grains Unique 1330 fps
17 grains 2400 1310 fps
18 grains 4227 1295 fps
20 grains N-200 1325 fps
22 grains 4198 1400 fps

250 and 255 grain Colt revolver bullets (250 grain gas check #454485)
26 grains 2400 1480 fps
27 grains 4227 1440 fps
28 grains N-200 1460 fps
34 grains 4198 1630 fps
37 grains 3031 1510 fps

Obviously the powders except Unique and N-200 are IMR.

Wow, these loads are light! The recoil calc puts it at 13lbs. Took it out for a one-shot test drive.....thought I had the ruger 10-22. I've been used to shooting loads in the high 30#'s (37 or so). Now, this is fun! Think I'll just step out and play "Rifleman" (except with 5 shots).

Perf -

You might check out our website (url below, look under levergun studies/data) - there you should find something like 200+ light/plinking loads for the 4570 and 450. For the loads jackfish mentions, a wad might not be a bad idea, but for our data, convective ignition is used throughout and using a wad would only defeat such (and screwup the uniformity of the ignition). Our first choice plinking 4570 bullet/powder combination has to be: 405gr lrnfp and vvn340... though Coyote Hunter speaks well of the HS6/7 loads... YMMV... but, have to agree with the delightfully low recoil numbers.

do shoot straight,

Perferator,
I use 8 grs of Unique, with a 300 gr. cast lead bullet. It doesn't need any filler, so reloading is a snap, and it gives mild recoil, and great accuracy in most of my .45-70's.
